Third-harmonic lasing at JAERI-FEL

Description

We have demonstrated FEL lasing at the third harmonic in JAERI-FEL driven by a superconducting linac. The lasing was achieved with a super enhanced gold-coated mirror tuned to 7 μm, which is a gold-coated copper mirror with Zn-Se multi-layer deposited on the surface. Lasing at the third harmonic is in the single-supermode regime with an average power of 15 W. The small-signal gain is estimated from the cavity-length detuning curve found to be 7.5%
